    I am wondering why I would need anymore that 120V at 12 amps. 3 miles per hour x 12 hours of time of use (TOU) (7 pm to 7 am) is 36 miles. My commute is 40 miles. On the weekend I get 60 hours of time of use. That is 180 miles.

    I am short 4 miles M-F for a total deficit of 20 miles by Friday. After 7 hours (on 120V) I am back to full on Saturday morning by 3 am.

    Since my TOU rate is 5 cents per kWh then life is good and "cheap". So every Monday I would be "full" at 238 miles.

    Now, if I could only charge at work. ;-)

    I have a friend who is a private contractor at Vandenberg AFB. He was all ready to buy an EV as he has a 120 mile commute every day. He works for Lockheed, and they would not let him charge during the day even at 120 v to make his commute possible. They have charging facilities close by, but they are for 'guests' only! Too bad! Would have been one more ICE off the road!!

    My company just put in EV chargers in the parking garage and I am super psyched. And I didn't even have to ask for them :biggrin:

    Well...


    1. In extreme cold winter conditions (e.g. -20C) you don't get any increase in range - the pack heater takes all the power.
    2. In moderate cold winter conditions you only get 1 mile per hour charging.
    3. You can't charge at off-peak rates if you're charging all day.
    4. Some people drive more than that in one day.

    Another way to look at it is how many hours plugged in per day vs driving and range. I drive 2 hrs a day. So therefore I can be plugged into 120V 22hrs a day. At max I would get 66 miles per day back. However , my daily commute is 95 miles.... So it wouldn't work for me. That's not factoring in that I drive fast so technically I use probably about 125 miles range to go 95 miles. Oh well. That's why I have a NEMA 14-50 at home.

    i work in a building managed by oxford, and apparently almost all oxford buildings provide free EV charging in the parkade (but you have to pay $35+ to park)

    I am very lucky in that my garage is heated. On the weekends, starting at 7 pm until 7 am on Monday, I get off peak rate of 5 cents per kW.

    To put this in perspective, many downtown parking garages in Boston charge $32 and include free EV charging. That's $32 per day​.

    Wow! You are so right. In Chicago, parking can be very expensive. And if memory serves me right, New York is frightfully expensive too.
